Design of the positioning piece 116 and the rotarygear 113 running in opposite is for fixing the rotation angle of therotation positioning and angle adjusting structure 11, and facilitatingits angle adjustment. As a matter of fact, the positioning piece 116 andthe rotary gear 113 are respectively a fixing part and a rotating part.The role of the fixing part is for fixing the rotation angle of therotating part, which is convenient for users to stop at a necessaryangle.

The above-mentioned rotation positioning and angle adjusting structure11 is just a typical, simple and convenient operation mode of thepresent invention, but it is not the only way. As a simple modificationof the present invention, the rotation positioning and angle adjustingstructure 11 can be a relatively simple plug-pin fixing structure (asshown in FIGS. 19 and 20), or two gears running in opposite structureused in other fields, or the structure of a circular concavo-convex diskas shown in FIGS. 21 and 22. At the same time, based on usage condition,it is possible to replace the mechanical structure in the presentembodiment with intelligently controlled mechanical structure amongexisting control methods such as electric control, magnetic control, oilcontrol, or air control. For example, when to prepare a football netwith a large support frame or a support frame for temporary largeposters, control the rotation of the post and the angular positioningafter rotation by electronic, magnetic, oil or air control will be moresuitable.

On the support receptacle 1 is provided a limited bulge 14 for limitingthe maximum rotation angle of the ball net lacing bar 3.

In the present embodiment, the ball net lacing bar 3 is a triangular netlacing bar with a section of triangular shape so as to better match theuse of the limited bulge 14.

As shown in FIGS. 1 to 8, the quantity of telescopic lacing bars 2 isarranged to be three, the three telescopic lacing bars 2 are parallel toeach other in space, and the cross section formed by the threetelescopic lacing bars 2 after being mounted on the support receptacle 1has a trianglular shape, wherein, a telescopic lacing bar 2 in themiddle plays an important role in stabilizing the entire base.

The connection sleeves include the support connection sleeves 5connected to telescopic lacing bars 2 located on both sides of supportreceptacle 1 and safe connection sleeves 43 connected to the telescopiclacing bars 2 located on the middle of the support receptacle 1.

The telescopic positioning assembly includes a limiting slot 45 providedon each connection sleeve and a limiting part 46 corresponding to thelimiting slot 45, meanwhile, on the telescopic lacing bar 2 iscorrespondingly provided a positioning slot, and the length of thetelescopic lacing bar is fixed after the limiting part 46 passes thelimiting groove and the positioning slot in turn. The limiting part 46may be a knife switch as shown in FIG. 11. In actual use, pulling theknife switch up, the telescopic lacing bar 2 is extendable to increasethe stability of the entire post. At present, there are no base lengthadjustable ball net posts commercially available. For the convenience ofoutdoor use, the base length is generally smaller than the width of thenet when fully extended (similar to FIG. 2). When total weight remainsconstant, the smaller the base length is, the worse the stability of theentire net post is. Therefore, it is proposed in the present inventionthat a technical solution wherein base length is adjustable, to overcomethe deficiency in the art of difficult base length adjustment, and onthe other hand, with the telescopic lacing bars, it is possible to storemore facilities or article, and the space occupation is reduced too.

In practical application, the above solution can also be used as aportable tent support, which facilitates tent construction and storage.The solution of the present invention satisfies consumers' demands forposts to be portable, easy to retract, and convenient to build.Therefore, the solution of the present invention should be vigorouslypromoted in the field of post manufacture so that products in this fieldcan better meet market demands.
